Nucleation Agent Choice of Li2O–Al2O3–SiO2 Glass Ceramic Having Ideal Micro Spherical Crystal Grains
The nucleation and crystallization of Li2O-Al2O3-SiO2(LAS) glass ceramic with one(P2O5, TiO2, ZnF2) and two nucleating agents(P2O5+TiO2, P2O5+ZnF2) are investigated by the differential thermal analysis(DTA)，X-ray diffraction(XRD) and the scanning electron microscopy(SEM). Research results show that the LAS glass ceramic with nucleating agent of P2O5 can obtain ideal micro spherical crystal grains and the crystallization behavior can be better controlled.
